Scientists Find a Pair of Proteins Control Supply Lines That Feed Cancer Cells
In human cancer cell and mouse studies, researchers from Johns Hopkins Medicine have found that a set of proteins work in tandem to build supply lines that deliver oxygen and nutrients to tumors, enabling them to survive and grow. The protein twosome, PADI4 and HIF-1, ramp up their activity under low-oxygen conditions that are typically found in a fast-growing tumor, allowing it to build new blood vessels that feed the cancer’s growth.
